Product details

Active production, AEC-Q101, 1.9 mOhm — the BOM-fit anchor

The BUK661R8-30C,118: AEC-Q101 qualification means the part has passed the automotive stress tests (H3TRB, intermittent op life, wire bond fatigue) required for tier-1 PPAP submissions — no separate qual run needed for under-hood or chassis-domain designs.

175°C junction — what it buys the thermal design

Rated operating junction temperature spans -55°C to 175°C. Gate charge is 168 nC at 10 V.

Package and mounting

The large exposed copper pad wicks heat into the board. The D2PAK package has a tab that is soldered to the board.

Sourcing: active, quoted per BOM

No single-source risk flagged — the part is widely stocked across the channel.

Frequently asked questions

What is the Rds(on) of BUK661R8-30C at 10V?

This is the spec that governs conduction loss — at 120 A the actual on-resistance will be higher due to self-heating, so use the normalised Rds(on) vs temperature curve in the datasheet for the real junction-temperature figure.

Is BUK661R8-30C RoHS compliant?

The part is listed as RoHS compliant per the NXP product documentation. The D2PAK package uses matte-tin plating on the leads, which is the standard RoHS-compatible finish for high-current power packages.
